IMPROVEMENT IN SUCKER-RODS.

Specification forming part of Letters Patent No. 119,232, dated September 26, 1871.

To all whom it may concern:

l Beit known that I, DANIEL JONES, of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Sucker- Rods 5 and I do hereby declare the following to be a full and correct description of the same,

reference being had to the accompanying drawing, in Whichl Figure lis a perspeceive view of the socket. Fig. 2 is a side View, partly in section, of the rod and socket united. Fig. 3 is a side view of the end of the rod prepared for insertion in the socket. Fig. 4 is a view of the inside ofthe socket after the molten metal has been poured in, the rod being removed to show the form of the metal when cold. v

The same letter indicates the same part in all the figures.

The nature of my invention consists in a new method of attaching the rod to the socket by making recesses in the socket and corresponding grooves in the end of the rod inserted in the socket, and running in molten metal into said grooves and recesses so as to fill them and thus bind the socket and rod iirmly and securely to- I prefer to use a fusible alloy Whichexpands in cooling.

In the accompanying drawing, which clearly illustrates the invention, R marks the rod, which is of hard Wood, and S the'socket, which is preferably made of brass. grooves g g g, Which run around it and are united In the rod are cut the by the longitudinal grooves e cut on both sides of the rod. Corresponding recesses are cut in the inside of the socket. The grooves e communicate with holes'p in the bottom of the socket, only one of which is shown in the drawing. In-

to one of these holes the molten metal is poured,

While the other serves as a vent. The metal which I prefer to use is a fusible alloy composed of tWo parts of antimony, nine parts of lead, and one part of bismuth. This alloy expands in cooling.

When the parts are prepared, the rod inserted in the socket, and the molten alloy poured in, it completely lls all the grooves and recesses in the rod and socket, and by its expansion compresses the Wood and thus binds the rod and socket securely together. The appearance of the metal Awhen cool and the rod has been removed from the socket is shown in Fig. 4.

What I claim, and desire to secure by Letters Patent, is-

A sucker-rod, composed of a grooved rod and recessed socket united by means of metal poured into the grooves and recesses in a molten state, as described.'

The above specification of my said invention signed and witnessed at Petroleum Centre this DANIEL JONES.
